Investigates the different levels in the visual system at which laterality effects may be elicited in children and adults in five different experiments. (LLK)

Differences between left and right hemispheric subjects in recalling information presented as pictures and words were studied. The hemisphericity of 133 college students (37 males and 96 females) was identified using the Human Information Process Survey. These subjects were shown 25 concrete nouns individually either as pictures or words. The data…

First-, third-, and fifth-grade children and adults performed a tactile shape-discrimination task. Changes in the magnitude of differences between performance in the left and right perceptual fields were examined. Results suggested that the right hemisphere becomes progressively more specialized for tactile spatial ability with increasing age.…

This study was designed to provide evidence concerning hemispheric independence in the visual modality of children and adults. Words and letters were shown either singly or in pairs. Hemispheric independence occurred more frequently among children when letters, as opposed to words, were shown. Results are discussed in terms of developmental models…
